Abstract

An extraction device for a biological fluid with an additive solution in which it is desirable for the additive solution to be present in a particular volume proportion to the biological fluid. The volume proportion of the additive solution is determined by the ratio of cross sections of two tubes, one which supplies the biological fluid to a collecting bag and a second which supplies the additive solution to a collecting bag. The tubes are periodically constricted in constriction areas by a pump. The tubes are configured so that the additive solution and the biological fluid only mix downstream of the constriction areas, thereby reducing the risk of supplying the additive solution to the source of the biological fluid. In an exemplary embodiment the biological fluid is blood collected from a patient or donor and the additive solution is an anticoagulant and/or preservation solution.
